I was originally going to use sch 10 stainless, but i'm not happy with the bends i'm able to get. since this is methanol i'm thinking of using a 16g stainless tube, and am wondering what guidlines you guys have on tube thickness for a methanol turbo header. With methanol would there be a large advantange using the sch 10 instead of the 16g. would an 18g tube be considered to thin.. I am planning on getting this stuff coated when its done also.
